Homebrew PCBs

Any suggestions on cutting circuit boards. I have used a bandsaw, but
it tends to be slow, dusty and inaccurate. I have tried paper shears,
but the board tends to get warped and is only good for about two
inches and it is too hard to cut any further.

I have seen a few references to using a diamond tile saw.  They have
wet tile saws with a diamond blade at home depot for $88 but it seems
that the blade would get gummed up with epoxy and not cut.
